Technical Field
[0001] The utility model relates to the technical field of field water sample collection, and particularly provides a field water sample collection device under ice. Background Technique
[0002] The continuous development of social economy has highlighted environmental problems, and water environment problems have become increasingly prominent, beginning to affect people's production and life. In recent years, more and more scholars have participated in the research of the water environment discipline, and field sampling, as one of the main means of this discipline research, has been more widely used. It is relatively easy to collect river and lake water samples in spring and summer. In the north, rivers and lakes will have obvious icing phenomena in winter. During the process of breaking ice to collect river and lake water under the ice, it is easily affected by broken ice, and the cold climate conditions seriously restrict personnel operation.
[0003] At present, the main equipment for field river and lake water body sampling is water samplers of various models. However, there is less research on water body sampling under the ice conditions of northern rivers and lakes in winter. It mainly relies on manually putting water samplers after breaking ice, and the sampling process completely depends on manual labor, resulting in a huge investment in labor costs.
[0004] Therefore, how to improve the existing field water sample collection device to reduce the investment in labor costs and avoid the pollution of water samples by broken ice during the water sample collection process has become an urgent problem to be solved. Content of the Utility Model
[0005] In view of this, the purpose of the utility model is to provide a field water sample collection device under ice to solve the problems of large labor cost investment and easy pollution of water samples by broken ice in the existing field water sample collection device.
[0006] The technical solution provided by the utility model is: a field water sample collection device under ice, including: an operation platform, support legs, a water sample collection bucket, a water sample collection bucket lifting structure, a positioning rod and a limiting plate. Among them, the support legs are fixed at the lower part of the operation platform. The water sample collection bucket includes a bucket body, a bucket cover, a spring and a counterweight. In the natural state, the bucket cover is hermetically covered above the bucket body through the spring, and the counterweight is fixedly connected to the bottom of the bucket body. The water sample collection bucket lifting structure is installed on the operation platform and connected to the water sample collection bucket for controlling the lifting of the water sample collection bucket. The positioning rod vertically penetrates the bucket cover and is provided with scales thereon. The limiting plate is located below the bucket cover and fixedly connected to the lower end of the positioning rod for overcoming the restoring force of the spring to make the bucket cover and the bucket body have a clearance fit.
[0007] Preferably, the support legs are telescopic support legs.
[0008] Further preferably, the bucket cover is a double-layer structure, including an upper bucket cover and a lower bucket cover. An inwardly disposed edge is provided at the upper part of the bucket body, and the edge extends between the upper bucket cover and the lower bucket cover. The edge is connected to the lower bucket cover by the spring. In the natural state, the edge abuts against the upper bucket cover under the action of the spring.
[0009] Further preferably, the counterweight is conical.
[0010] Further preferably, a water discharge port is provided at the lower part of the bucket body.
[0011] Further preferably, the water sample collection bucket lifting structure includes a wire winding motor, a wire winding wheel and a wire rope. The wire winding wheel is fixed on the output shaft of the wire winding motor. One end of the wire rope is wound around the wire winding wheel, and the other end of the wire rope is connected to the bucket body.
[0012] Further preferably, a level is provided at the upper part of the operation platform.
[0013] For the field ice-bottom water sample collection device provided by the present invention, the operation platform can be erected at the ice surface opening position through the support legs. The sampling depth can be located through the scale on the positioning rod. The lifting of the water sample collection bucket can be controlled through the water sample collection bucket lifting structure. By providing a limit plate at the lower part of the positioning rod, the bucket cover can be opened in cooperation at the specified water sample collection depth to complete the sampling. After the sampling is completed, during the process of lifting the water sample collection bucket, the bucket cover of the water sample collection bucket can be automatically closed to prevent the water sample inside the bucket body from being polluted.
[0014] The field ice-bottom water sample collection device provided by the present invention can solve the problems of large investment in human cost and easy pollution by broken ice during the water sample collection process of the existing field water sample collection device, and can also accurately control the sampling water depth. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The following further describes the present invention in detail with reference to the drawings and embodiments:
[0016] Figure 1 It is a schematic structural diagram of a field ice-bottom water sample collection device provided by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following will further explain the present invention with reference to specific implementation embodiments, but the present invention is not limited thereto.
[0018] Such as Figure 1As shown in the figure, the utility model provides a field underwater ice water sample collection device, which is characterized by comprising an operation platform 1, support legs 2, a water sample collection bucket 3, a water sample collection bucket lifting structure 4, a positioning rod 5 and a limiting plate 6. Among them, the support legs 2 are fixed to the lower part of the operation platform 1. The water sample collection bucket 3 includes a bucket body 31, a bucket cover 32, a spring 33 and a counterweight 34. In the natural state, the bucket cover 32 is hermetically covered above the bucket body 31 through the spring 33. The counterweight 34 is fixedly connected to the bottom of the bucket body 31. The water sample collection bucket lifting structure 4 is installed on the operation platform 1 and connected to the water sample collection bucket 3 for controlling the lifting of the water sample collection bucket 3. The positioning rod 5 vertically penetrates the bucket cover 32 and is provided with scales thereon. The limiting plate 6 is located below the bucket cover 32 and fixedly connected to the lower end of the positioning rod 5 for overcoming the restoring force of the spring 33 to make the bucket cover 32 and the bucket body 31 in clearance fit.
[0019] For this field underwater ice water sample collection device, the operation platform can be erected at the ice surface opening position through the support legs, and water samples at a specified depth can be collected without removing the broken ice in the ice hole. During the process of collecting water samples, after setting the clearance between the limiting plate and the bucket cover, control the synchronous falling of the water sample collection bucket and the positioning rod. After reaching the specified sampling depth, fix the positioning rod. The bucket body will continue to fall driven by the counterweight. When the bucket cover is restricted by the limiting plate, a clearance is generated between the bucket body and the bucket cover, and the water sample enters the bucket body through the clearance. After collecting the water sample, control the water sample collection bucket to rise through the water sample collection bucket lifting structure. During the rising process, the spring drives the bucket cover to return to the initial state under the action of the restoring force, that is, the bucket cover is hermetically covered above the bucket body, which can prevent the water sample inside the bucket body from being polluted.
[0020] As an improvement of the technical solution, as Figure 1 shown, the support legs 2 are telescopic support legs for changing the height of the operation platform 1.
[0021] Among them, there are various ways to control the separation of the bucket cover and the bucket body through the limiting plate, which can be selected according to needs. As an improvement of the technical solution, as Figure 1As shown in the figure, the bucket lid 32 has a double-layer structure, including an upper bucket lid and a lower bucket lid. An inwardly disposed rim is provided at the upper part of the bucket body 31. The rim extends between the upper bucket lid and the lower bucket lid. The rim is connected to the lower bucket lid by the spring 33. In the natural state, the rim abuts against the upper bucket lid under the action of the spring 33. During the process of collecting water samples, when the bucket lid falls with the bucket body until it is limited by the limiting plate, the bucket body continues to fall under the gravity of the counterweight until the spring is compressed to the limit position. At this time, a gap is generated between the bucket lid and the bucket body, and the water sample will enter the bucket body through the gap. After collecting the water sample, control the water sample collection bucket to rise. During the rising process, the spring drives the bucket lid to return to the initial state under the action of the restoring force, closing the bucket body.
[0022] As an improvement of the technical solution, as Figure 1 shown, the counterweight 34 is conical and is used to push aside broken ice to facilitate sinking.
[0023] As an improvement of the technical solution, as Figure 1 shown, a water discharge port 35 is provided at the lower part of the bucket body 31 to facilitate water discharge.
[0024] As an improvement of the technical solution, as Figure 1 shown, the lifting structure 4 of the water sample collection bucket includes a wire winding motor 41, a wire winding wheel 42 and a wire rope 43. The wire winding wheel 42 is fixed on the output shaft of the wire winding motor 41. One end of the wire rope 43 is wound around the wire winding wheel 42, and the other end of the wire rope 43 is connected to the bucket body 31.
[0025] As an improvement of the technical solution, as Figure 1 shown, a level 7 is provided at the upper part of the operation platform 1 to adjust the levelness of the operation platform.
[0026] The specific embodiments of the present invention are written in a progressive manner, emphasizing the differences between each embodiment, and the similar parts can be referred to each other.
[0027] The above has described in detail the embodiments of the present invention with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
